BD15GA3MEFJ-LBH2 Application Field and Working Principle

The BD15GA3MEFJ-LBH2 is a 3-terminal low dropout linear voltage regulator module comprising of a epitaxial high speed BJT, a low dropout voltage (To-220F) regulator, an output capacitor and a NPN anti-saturation protection circuit chip. It is essentially a high speed, low power, linear voltage regulator that can accurately regulate the output voltage over a wide input voltage range.

The BD15GA3MEFJ-LBH2 is typically used in automotive applications such as engine control modules, body control modules (ECUs) and electronic control units (ECUs). It is also suitable for portable devices, cellular phones, and power supplies.

Working Principle

The working principle of this voltage regulator is to reduce the input voltage to the desired output voltage by applying a series of BJT (Bipolar Junction Transistor) stages in the common mode circuitry. The input voltage is reduced through the low-noise BJT before it is presented to the base of the n-channel MOSFET where it can be further reduced to the desired output voltage.

The BD15GA3MEFJ-LBH2 voltage regulator also features an NPN anti-saturation protection circuit to protect against over-current or output voltage overshoot. This circuit is designed to protect the internal BJT or MOSFET from current overload or voltage surges.
